Just an unofficial design concept, but damn, this is sexy. This is exactly what Windows needs - a combination of the old and new, leading to something seemingly far more usable than the monstrosity that is Metro in Windows 8.

"(not everyone is a fan of osx but you can't deny it's elegant and does not limit functionality the same way metro or this design does).

The great thing about OS X is that, for the things it does limit, it is very easy to implement using open software. OS X's BSD underpinnings make it a snap to port GNU/Linux software over. So, you get the elegance and ease of use alongside the power to get stuff done and use the old tools you're used to. "

Yes... the next version (mavericks) does not appear to ruin what was good about it. Even on the current release they implemented the Launchpad in a way that power-users can ignore it easily, unlike launching apps win8. (I still don't get the appeal of that kind of full screen app launcher on a big screen)
